The risk of ectopic pregnancy following fertility treatment with assisted reproduction (ART) is small but significantly higher than found in natural conceptions. Now, a nationwide population-based analysis of all ART pregnancies ...

A proposal in Hawaii's Legislature would expand a state mandate on fertility treatments to include same sex couples and single women, updating a law that now only offers such benefits to women who are married to men.

The psychological impact and private agony of infertility must be carefully considered by healthcare professionals, suggests a new review, published today (Friday 10 April) in The Obstetrician & Gynaecologist (TOG). The review ...

When scientists exposed pregnant mice to levels of bisphenol A equivalent to those considered safe in humans, three generations of female mouse offspring experienced significant reproductive problems, including declines in ...

A potent risk factor for developing major depressive disorder (MDD) during fertility treatment is something health providers are likely not even looking for, according to new research from San Francisco State University.

Women who have difficulty getting pregnant often turn to in-vitro fertilization (IVF), but it doesn't always work. Now scientists are taking a new approach to improve the technique by studying the proteins that could help ...

Birth outcomes for babies whose mothers used assisted reproductive technology (ART) are better in some cases, and worse in others, than for subfertile women who did not use ART, according to a first-of-its-kind study led ...

Fertilizer

Fertilizers are chemical compounds applied to promote plant and fruit growth. Fertilizers are usually applied either through the soil (for uptake by plant roots) or, by foliar feeding (for uptake through leaves).

Fertilizers can be placed into the categories of organic fertilizers (composed of decayed plant/animal matter), or inorganic fertilizers (composed of simple chemicals and minerals). Organic fertilizers are 'naturally' occurring compounds, such as peat, manufactured through natural processes (such as composting), or naturally occurring mineral deposits; inorganic fertilizers are manufactured through chemical processes (such as the Haber process), also using naturally occurring deposits, while chemically altering them (e.g. concentrated triple superphosphate).

Properly applied, organic fertilizers can improve the health and productivity of soil and plants, as they provide different essential nutrients to encourage plant growth. Organic nutrients increase the abundance of soil organisms by providing organic matter and micronutrients for organisms such as fungal mycorrhiza, which aid plants in absorbing nutrients. Chemical fertilizers may have long-term adverse impact on the organisms living in soil[citation needed] and a detrimental long term effect on soil productivity of the soil[citation needed].
